Abstract:

La présentation sur ribosome (en anglais, ribosome display) est une méthode d’évolution moléculaire et de sélection de banques peptidiques et protéiques. Le ribosome display est réalisé in vitro dans un milieu acellulaire et repose sur la formation d’un complexe ternaire ribonucléoprotéique entre l’ARN, le ribosome et la protéine. Le ribosome display est devenu de nos jours l’une des méthodes de présentation les plus utilisées. Elle a notamment permis le criblage et la sélection de peptides, de protéines, d’échafaudages moléculaires afin d’améliorer leur affinité, leur spécificité, leur activité catalytique ou même leur stabilité. Cette revue présente la mise en œuvre du ribosome display et les applications qui découlent de l’utilisation de cette technologie.

Abstract:

Le polymorphisme génétique de la protéine prion ovine associé à des degrés divers de résistance ou de sensibilité à la tremblante ouvre une voie féconde pour comprendre le lien entre les propriétés structurales de la protéine et le mécanisme du développement de la pathologie. Les travaux menés par les équipes de l’INRA, en collaboration avec d’autres équipes nationales, ont apporté des renseignements inattendus sur la stabilité et la convertibilité des variants naturellement rencontrés dans les troupeaux européens. Les mécanismes, au niveau atomique, sous-tendant ces caractéristiques ont pu être explicités par la détermination cristallographique de la structure tri-dimensionnelle de la protéine ovine, apportant en même temps une première information expérimentale sur la structure de la protéine pathologique. Des formes intermédiaires de repliement, sous forme d’oligomères solubles, ont pu être isolées in vitro, et se sont révélées neurotoxiques, ouvrant de nouvelles pistes de recherche vers les déterminants respectifs de la mort neuronale et de la réplication du prion.

Abstract:

Les anticorps sont désormais devenus d’une utilisation courante dans un large champ thérapeutique qui n’est plus restreint à la cancérologie et à l’inflammation. Cette explosion du domaine conduit à des besoins nouveaux qui peuvent être mieux remplis par des molécules inspirées mais différentes des anticorps classiques. En particulier, la molécule anticorps a de multiples fonctions qui ne sont pas toujours nécessaires, comme sa capacité à recruter les cellules du système immunitaire, à se lier de façon bivalente à sa cible ou à présenter une demi-vie plasmatique élevée. En revanche, dans la grande majorité des applications, sa remarquable capacité à reconnaître spécifiquement sa cible moléculaire et surtout sa diversité de reconnaissance doivent être conservées. De plus, les anticorps sont des molécules de très haut poids moléculaire, coûteuses à produire et qui présentent des propriétés physicochimiques limitées ne permettant pas leur utilisation dans des milieux agressifs. Finalement, dans certaines applications thérapeutiques, la grande taille de la molécule (environ 150 kDa) peut également limiter sa diffusion dans les tissus et empêcher la reconnaissance de certaines structures moléculaires peu accessibles. Pour répondre à ces limitations, de nombreux formats alternatifs aux anticorps entiers ont été développés au cours de ces vingt dernières années. Les applications couvrent les domaines de la biotechnologie, du diagnostic in vitro et in vivo et de la thérapie. Deux grandes familles de molécules permettent de couvrir ce champ et seront présentées dans cette mini-revue. Une première famille s’appuie sur la diversité naturelle des anticorps mais en en réduisant la taille, comme les fragments d’anticorps classiques (Fab, scFv) ou ceux provenant des camélidés ou des requins (VHH, V-NAR). La deuxième famille a été développée en partant des propriétés finales désirées et notamment la stabilité en milieu extrême et la productivité en système simple et économique de production comme l’utilisation de bactéries et en y greffant des propriétés de liaison comparables aux anticorps par des méthodes d’évolution moléculaire dirigée in vitro. Cette mini-revue se concentrera sur les molécules les plus avancées, mais le domaine est en très forte et rapide expansion. Il faut noter que beaucoup de ces molécules, voire ces approches, sont couvertes par des brevets et sont souvent développées dans le cadre de jeunes sociétés innovantes dont certaines ont déjà été rachetées par de grands groupes de la pharmacie.

Abstract:

Abstract We assessed the stability of alpha-fetoprotein (AFP) in clinical specimens in the presence and absence of serum and albumin, at different temperatures and concentrations. We find it depends on both AFP concentration and incubation temperature. Dilution of most specimens with either phosphate buffer or phosphate-buffered saline or by immunoelectrodiffusion resulted in some loss of AFP. Attempts to stabilize AFP during either sample dilution or incubation by use of albumin in concentrations up to 1 g/L did not protect it from inactivation unless normal human serum was also included. Frozen AFP solutions were less stable than solutions stored at 4 degrees C. AFP was most stable when lyophilized and stored desiccated. The AFP-inactivation curves were usually nonlinear. Apparently both polymerization and degradation occur simultaneously as AFP loses its activity. Proteolytic enzyme inhibitor and sulfhydryl reagent not only failed to protect it from inactivation, they appeared to speed it.

Abstract:

The stability of an in-vitro diagnostic (IVD) medical device reagent is the ability to maintain the performance characteristics over a defined time interval. The stability studies are performed to demonstrate that the product remains viable under the specified storage condition until the claimed time period. Since, stability of the IVD cannot be directly assessed through accuracy, performance attributes or customer testing; it is the responsibility of the manufacturer to evaluate the performance of the product by identifying critical factors affecting the stability through developing stability plan, stability protocol and conducting real-time stability studies, accelerated stability studies, in-use stability studies and transport simulated stability studies.

Abstract:

Briggs Nurseries, Inc. has used micropropagation as method of vegetative propagation for over 20 years. Genetic stability and uniformity of plants that are produced and sold is of the utmost concern to the commercial plant propagator. Genetic stability may be accomplished by ensuring that all shoots formed in vitro are of axillary origin and by reducing shoot proliferation rates through the use of lower cytokinin concentrations in the culture medium. Excision and removal of callus during transfer is also necessary to ensure that shoots develop from axillary buds. Various factors that may influence genetic variability and its frequency of in vitro derived plants will be discussed with an emphasis on how to reduce them. Three sources of variation with tissue culture derived plants will also be reviewed (Swartz, 1991): a) source plant variability, b) genetic changes in vitro, and c) epigenetic or physiological adaptation.

Abstract:

Cucurbita pepo L. which is a member of Cucurbitaceae family, is a one-year plant with herbaceous stems, broad leaves and superficial scattered roots. Monoic flower structure in the Cucurbitaceae family and the differences in the maturing time of male and female organs in flowers cause an increase in the foreign fertilization rate. Therefore, there may be positive or negative changes in the existing characteristics of the species. Micro-propagation method can be performed in pumpkin species for clonal propagation, but genetic stability after tissue culture is an important consideration. Chromosome number and morphology are primary cytogenetic parameters that must remain stable after in vitro propagation. We analyzed plants of different hybrid pumpkin genotypes cultivated in our country (Ardendo, Angelina, Torpido, Roni, Sena Hanım) cytogenetically in order to determinate their stability level. Cotyledon nodes, nodes, shoot apex, hypocotyl and internode explants were prepared from the 4-week old C. pepo seedlings by making a horizontal slice through the hypocotyl region. Cotyledonary node explants produced multiple shoots and callus regeneration in MS medium in the presence of N6-benzylamino-purine BA 1 mg/L in Torpido genotype. Elongated shoots were excised from shoot clumps and transferred to rooting medium. The best root generation was obtained from Torpido and the most successful explant type for root regeneration was determined in cotyledon nodes as in shoot regeneration and MS medium without plant growth regulator showed the best root regeneration. The rooted plants were hardened in small pot containing standardized garden soil, well developed plant transferred to greenhouse. The chromosome number and karyotype analysis were determined in control and in vitro propagated Cucurbita pepo L. plants and ploidy levels were confirmed to be 2n = 40.

Abstract:

The interface between kinetochores and microtubules in the mitotic spindle is known to be dynamic. Kinetochore microtubules can both polymerize and depolymerize, and their dynamic behavior is intimately related to chromosome movement. In this paper we investigate the influence of kinetochores on the inherent dynamic behavior of microtubules using an in vitro assay. The dynamics of microtubule plus ends attached to kinetochores are compared to those of free plus ends in the same solution. We show that microtubules attached to kinetochores exhibit the full range of dynamic instability behavior, but at altered transition rates. Surprisingly, we find that kinetochores increase the rate at which microtubule ends transit from growing to shrinking. This result contradicts our previous findings (Mitchison, T. J., and M. W. Kirschner, 1985b) for technical reasons which are discussed. We suggest that catalysis of the growing to shrinking transition by kinetochores may account for selective depolymerization of kinetochore microtubules during anaphase in vivo. We also investigate the effects of a nonhydrolyzable ATP analogue on kinetochore microtubule dynamics. We find that 5' adenylylimido diphosphate induces a rigor state at the kinetochore-microtubule interface, which prevents depolymerization of the microtubule.
